Storm and screen sash



June 23, 1942. c. A. SMITH STORM AND SCREEN SASH Filed Feb. 5, 1941 Patented June 23, 1942 UNITED STATES 5 Claims.

This invention is a novel storm or screen sash adapted to be applied to conventional window frames or the like; and the principal object thereof is to provide interchangeable storm or screen sashes adapted to be secured in the window frame exteriorly of the main window sashes and consisting of pairs of upper and lower sash sections which may carry either glass panes or screening, each sash section being insertable into position in the window frame from the interior of the room or building, and said pair of sash sections locked into place therein utilizing a hardware latch on the top rail of the upper sash section, and utilizing a locking bar, disposed between the upper and lower sash sections having its ends entering suitable slots in the sides of the window frame.

I will explain the invention with reference to the accompanying drawing which illustrates one practical embodiment thereof, to enable others to adopt and use the same; and will summarize in the claims, the novel features of construction, and novel combinations of parts, for which protection is desired.

In said drawing:

Fig. 1 is a front elevation, partly broken away, showing my novel storm or screen sash mounted in a window frame.

Fig. 2 is an enlarged vertical section on the line 22, Fig. 1.

Fig. 3 is an enlarged horizontal section on the line 3-3, Fig. 1.

Fig. 4 is a perspective View of an end portion of the locking bar.

Fig. 5 is a plan view of the top rail of the upper sash section showing the hardware latch mounted therein.

Fig. 6 is a section on the line 6-6, Fig. 5.

As shown, the window frame is of conventional type, the same consisting of an open rectangular frame A housing the customary glazed upper and lower window sashes B and C which are vertically slidable therein between guide strips D, the lower rail ofuppersash B and the upper rail of lower sash C overlapping when the window is closed, and the upper sash B when lowered being disposed in front of lower sash C. Frame A is adapted to be inserted in the opening in wall W; and at the front of frame A is an open trim frame comprising a top member E, said members F, and a sill G, the members E and F contacting the exterior wall W of the building adjacent the window opening in the usual manner. The above parts are conventional and form no part of my present invention.

In order to mount the storm or screen sash sections in the window frame I provide an inverted U-shaped frame I closely fitted within the opening formed by the members E and F, the legs of frame I being reinforced at their points of connection to the base by corner clips Ia (Fig. 1) or the like. Frame I closely fits within the edges of the opening in the trim frame E and F, and the distance between the vertical legs of frame I is somewhat less than the distance between the vertical guides D for the glazed window sashes B and C, as indicated in Fig. 3. The frame I has an inwardly extending flange ID at its outer edge for the purpose of limiting the outward movement of the storm or screen sashes, hereinafter described, which are inserted into frame I from the interior of the room when both glazed window sashes B and C are in lowermost position.

The pairs of storm or screen sashes comprise lower and upper sash sections 2 and 3 which may carry either screens or glass panes respectively. The lower sash section 2 is of width adapted to fit within the frame I with its outer surface contacting the flange ID as shown in Fig. 3, said sash 2 extending substantially half of the height of the opening in the frame I, and the lower rail of sash 2 resting directly on sill G. Since the distance between the vertical legs of the frame I is less than the distance between the vertical sash guides D, said lower sash section 2 may be readily inserted into said position in frame I when the glazed window sashes B and C are both in lowermost position, by placing the lower rail of section 2 between the vertical legs of the frame I at a point opposite the upper end of the lowered sash B while the sash is in the inclined position indicated in dotted lines in Fig. 2, and then lowering the section 2 directly into the position shown in full lines in Fig. 2 directly opposite the lowered sash B.

The upper face of the top rail of lower sash section 2 is provided with an axially disposed V-shaped groove 2m extending the full width of the sash adapted to receive the correspondingly shaped lower face of a locking bar 4 (Fig. 4) which is somewhat longer than the'width of sash section 2. One end of locking bar 4 is entered into a recess Ia: (Fig. 1) in one vertical leg of frame I disposed opposite the upper rail of sash 2, and the other end of bar 4 is fitted into an elongated slot Iy (Figs. 1 and 2) in the opposite vertical leg of frame I, the lower end of which slot terminates opposite the upper rail of sash section 2 when same is in the position shown in Fig. 1. Slot Iy is of such length that locking bar 4 during insertion or removal may be readily tilted as shown in dotted lines in Fig. 1 while its opposite end is engaged in the slot Ia: and after the sash 2 is in proper position. The locking bar 4 when thus positioned will hold the upper rail of lower sash section 2 against inward movement with respect to the frame I, the lower rail of sash 2 being held in position by the ledge formed between sill G and the adjacent guide D for the glazed sash B, as indicated in Fig. 2.

When the parts are thus positioned the upper sash section 3 may similarly be inserted into frame Lfrom the interior of the room, the upper sash 3 also having a V-shaped groove 3a: in the lower face of its lower rail adapted to seat upon the correspondingly shaped upper face of locking bar 4 to hold the lower rail of section 3 against inward movement of the frame I, the section 3 being inserted into frame I in the tilted position indicated in dotted lines in Fig. 2. When thus seated on the locking bar 4, the sash section 3 is swung into vertical position between the legs of frame I.

Embedded in the upper rail of the upper sash section 3 is a pivoted latch 5 (Figs. 2, 5 and 6) mounted in a frame 6 disposed in a slot in the said rail, said latch 5 having a non-circular bore 5a (Fig. 6) registering with a transverse bore in the sill whereby the non-circular shank Ia of a key I may be inserted therein to swing the latch 5 from lowered position shown in full lines in Fig. 6 into projected position shown in dotted lines in Fig. 6, said latch when so swung entering a slot in the underside of the upper member of frame I as clearly indicated in Fig. 2, the latch thus holding the upper rail of the sash section 3 from inward movement with respect to the frame I.

In removing the sashes 2 and 3 from thei'rame I the glazed sashes B and C should be lowered, and key I inserted into the latch 5 and revolved to retract the latch into the position shown in full lines in Fig. 6. The upper end of the upper sash 3 can then be tilted inwardly as shown in dotted lines in Fig. 2, and sash 3 removed from its position on the locking bar 4. When thus removed the end of the lock bar engaging the elongated slot Iy may be raised to the position shown in dotted lines in Fig. 1 to release same from the opposite slot ly and the locking bar 4 removed, whereupon the lower sash 2 may be pulled upwardly within the frame I until same assumes the position shown in dotted lines in Fig. 2 wherein same may be withdrawn through the window opening above the lowered sashes B and C, in the same manner that the upper sash 3 was removed.

By the above construction both sash sections 2 and 3 are securely locked in frame I merely by the use of locking bar 4 which engages the slots Ia, Iy, in the sides of frame I, the locking bar being disposed between the upper and lower sashes; also by means of the hardware latch 5, no other fastening means being required. The sashes 2 and 3 when thus secured in position completely fill the opening bounded by the frame I and cannot be removed from the exterior of the building without tearing out the frame I. Moreover, both sashes 2 and 3 may be inserted and removed from their positions in the window frame through the window from the inside of the building when the glazed Window sashes B and C are in lowermost position. The pairs of sash sections 2 and 3 may be provided with screening or glass panes; or if desired, one pair of sashes 2 and 3 may be provided with screening, and another pair provided with glass panes, so that said pairs are interchangeable while the same securing means may be used for holding either the storm sashes or screen sashes in their locked positions in frame I.

Iclaim:
